FYI Susan,
I just completed installing KB 2993651 on my TEST partition after UNInstalling KB 2982791 but NOT KB 2975791 (the Rollup/Update 2).
I have not had any issues at all, NOW or before with the original Patch Tuesdays' offerings in their entirety.
I am in Calgary, Alberta, Canada, my ISP is Shaw Cable, but I only us OpenDNS (now in Vancouver as well I believe, they are spreading there love far and wide) I have had no DNS issues.
Question?
Do you now if the DNS issues are because of the BIG IRON Routers, at the various levels of the Internet, using old Cisco router's which have a limitation in the DNS Lookup table to 512 K entries? We saw a problem because of that earlier in the month due
to a Verison mistake which was easily rolled back, THAT time. One notable site affected was "LastPass", but many more simple just disappeared.
Thanks again,
Crysta
